BD9615MUV-LBE2 ROHM

Datasheet 3.5V to 60V Input 1ch Boost DC/DC Controller BD9615MUV-LB General Description Key Specifications This is the product guarantees long time support in Input Voltage Range: 3.5V to 60V Industrial market. Reference Voltage Precision: (Ta=25C) 0.8V1.5% (Ta=-40C to +105C) 2.0% BD9615MUV-LB is a low side MOSFET controller with Frequency Range: 100kHz to 2500kHz high withstand voltage (60V). It is suitable for circuits Operating Temperature Range: -40C to +105C requiring low side FET such as boost and flyback, and it can be used in various applications. Package W (Typ) x D (Typ) x H (Max) An external resistor can adjust the switching frequency VQFN16KV3030 3.00mm x 3.00mm x 1.00mm from 100kHz to 2500kHz. It reduces the total mounting area because It can operate at extremely high switching frequency. In addition, it has an external clock synchronization function to perform noise management. BD9615MUV-LB has Thermal Shutdown (TSD), Over Voltage Protection (OVP), and Over Current Protection (OCP) to prevent damage caused by various abnormal modes.
